8.9 Non-condensing gases
i The drain valve (V6) for non-condensing gases
opens if the pressure in the refrigerant cylinder
is higher than the set opening pressure (normally
between 12 and 14 bar).
i The pressure of the internal refrigerant cylinder
increases during the recovery phase and when
preparing the refrigerant.
i The safety valve (V5) opens at a factory set
pressure (approx. 18 bar) to limit the pressure in
the internal refrigerant cylinder.
